Abstract
A control device for a fan motor () which cools a condenser () of a vehicle air conditioner includes a temperature sensor () which detects a temperature of an air that has passed through an evaporator () of the vehicle air conditioner; and a controller (). The controller () functioning to calculate a reference value (Ds) of an airflow generated by a rotation of the fan motor (); calculate a correction value (DUP, DUPT) of the airflow on the basis of the detected air temperature (Tair); set a target airflow (TDR) on the basis of the reference value (Ds) and correction value (DUP, DUPT) of the airflow; and control the rotation of the fan motor to effect the target airflow (TDR).
